A Navy admiral based in Connecticut says the submarine force is planning its next Arctic exercises for the spring of 2014.
But Rear Adm. Kenneth Perry said in an interview Tuesday that there is some uncertainty over whether they will take place due to budget pressures in Washington.
The submarine force has been conducting exercises under the ice every few years to test and assert its capabilities in a region with frigid water and acoustics that present challenges unlike any other ocean.
Perry is the Groton, Conn.-based commander of all U.S. attack submarines based on the East Coast. He said one of the Virginia-class attack boats in Groton is being prepared for the next Ice Exercise.
